COIN-OPERATED LOCK FOR TURNSTl LES.

SPECIFICATION forming part of Letters Patent No. 439,107, dated October 28, 1890.

Application filecl June 29,1889.

To all whom it may concern:

Be it known that I, HENRY CASPAR, a citizen of the United States, residing at New 0rleans, in the parish of Orleans and State of Louisiana, have invented certain new and useful Improvements in a Coin-Operated Lock; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in a coin-operated lock for turnstiles, doors, and Other similar devices in which a shaft having a stationary cylinder placed thereon and a lock operated by a coin placed within the cylinder is made to operate in conjunction with a series of doors; and the object of my invention is to provide a coin-operated lock for all places where fare is demanded before admission is gained, thus enabling fare to be collected in an automatic manner by causing coin to be deposited within the lock before the applicant for admission is permitted to pass through the entrance.

In the drawings, Figure l is a perspective view of a turnstile or a door of like character having my improvements applied thereto. Fig. 2 is a partial horizontal sectional view on the line as a: of Fig. 1, showing the ratchet and stay-bolt. Fig. 3 is a central vertical view showing the cylinder-case in which the lock and money-box are placed, and Fig. 4. is a central vertical sectional view taken at right angles to that shown in Fig. 3. Fig. 5 is a detail view, partly in section, showing the interior of the lock, the periphery of the cylinder, and the position of doors relatively thereto. Fig. 6 is a detail sectional view showing the position of the shaft and rotating arms to which the doors are attached when in place. Fig. 7 is an enlarged side view of the lock with the side removed, showing the coin before operation. Fig. 8 is a top sectionalview of the same. Fig. 9 is a view similar to Fig. 7 after operation, showing the coin in dotted lines as it passes down out of the look into the the money-box; and Fig. 10 is a view similar to Fig. 8, showing the parts after the coin has operated.

Referring more particularly to the drawings, A indicates the posts, B the bottom, and C the top, of a frame within which my im- Serial No. 315,974. (No model.)

proved stile is located. Secured at its ends to the top and bottom of the frame is a post E, around which the wings or doors D are arranged to swing or rotate. Arms 9 are se cured to a ring or sleeve 11 and secure the doors in position. Balls 10 maybe placed between the ring 11 and a base-piece K at the bottom of the post E to prevent undue friction in swinging the doors around the post.

Instead of making the post out of a single piece having a shell or cylinder G formed at the central portion, it can be made of two parts having the adjacent ends secured to or connected with the casing in any suitable manner. A rim F is placed in the inner edge of each of the wings, so that they will pass freely around the cylinder withoutcoming in contact with it. The rims are secured at their ends to rings around the shaft similar to the ring 11, and the upper ends of the doors may be secured to a ring by means of" arms 9, in the same manner as the lower ends.

Located within the cylinder G is the lock 3, which fits within an opening in the cylinder at one end, and is secured to the opposite side of the cylinder by means of the arms 1 and 2 and the screws 0, which pass through the cylinder into the ends of the arms. The bolts T and Q extend entirely through the frame or shell of the lock and project therefrom at each end. The rear portion of each bolt is reduced or turned down, and upon the reduced portions are spiral springs P. The rear ends of these springs have a bearing against the rear inner wall of the lock-casing, and the forward end of the spring on the bolt Q bears against a stud on the stem of the bolt, as better shown in Figs. 9 and 10 of the drawings, while the forward end of the spring of the bolt T has its bearing against the lateral arm W of the other bolt, so that both bolts are normally held with their outer ends advanced. The forward or outward movements of these bolts T and Q are limited by means of pins 13. One of the bolts T has a laterally-projecting arm W, through which the other bolt passes. A latch V is pivoted at rear end of the lock, and has its free end provided with bolt T. The outer end of the bolt Q isl beveled or inclined, so that when the wings D are rotated around the post E the rim F will engage with the beveled portion of the bolt and push it back through the lock until it will permit the rim and door to go past it. The outer end of the other bolt T also projects out into the path of the rim F; but as it is not beveled or inclined the rim strikes squarely against its side and prevents the door from rotating further. In this manner the stile is locked and will not let any person past it until the square-ended bolt T has been withdrawn into the casing.

In order to unlock the bolt T or release it so that it can be withdrawn into the look, a piece of money Z, of the denomination required as the price of admission, must be dropped into the slot S in the top of the cylinder G. The coin passes down through the chute R into the lock 3, through a slot g in its top and falls upon a plate or latch T, which is pivotally secured at one end and covers the exit 5 at the bottom of the frame.

The bolt Q has one of its sides cut away directly under the slot 9, forming a shoulder g, which will bear against the edge of the coin and carry it back against the end of the latch V, when the bolt is forced in by the pressure of the arm F against its outer or beveled end. As the end of the latch is above the center of the coin, the rearward movement of the coin will cause it to pass in under the end of the latch and raise the shoulder 1; out of engagement with the arm W, and thus release the bolt T. By this time the edge of the coin below the latch has been forced against the arm IV and pushes it back, andwith it the bolt T. Thus by the time the door D has passed around the cylinder far enough to push the bolt Q entirely in out of the way, the bolt T has also been carried in out of the way, and the door can be swung on around and permit the passage of the person behindit.

To prevent the stile from being continuously rotated with the payment of only a single admission fee, the end of the plate T is extended so as to project beyond the casing G below the bolts Q and T into the path of the wings D, and thus be carried around with the wings. This swinging of the plate draws it from under the coin and lets it fall through the opening 5 into the bottom of the look into the money-box t below; but as this does not happen until after the rim F has passed over the end of bolt T the further rotation of that door is not interfered with; but as soon as the rim has cleared the end of bolt T the springs P forces both bolts back into their original position, which will prevent the passage of another door until another fare has been deposited in the slot, as above described.

To prevent the admission of a second fare into the look before the parts have returned to their normal position, the end of a hookshaped arm X is swung in under the slot y and obstructs the passage, so that another coin cannot pass through until the arm has been withdrawn. The arm X is secured to a spring-actuated post X and is operated by means of the plate T, which presses against a pin t, that projects from the post X. The rear edge of the plate T strikes against the pin t and swings the arm X just before the coin in the lock has been discharged into the in oney-box below.

The plate T is preferably provided with a recess in its rear edge, which will permit of the plate being carried back its required distance without coming in contact with the post X. A coiled spring engages with the plate near its pivotal end and returns it to its normal position as soon as its free end is released by the passage of the door D.

WVhenever it is desirable to empty the money-box, it is readily done by unlocking the door 7 in the side of the cylinder Gby the key 6 and swinging it back on its hinges 8. The contents of the box can then be removed, after which the door is closed and locked, and the device is again ready for operation.

To prevent the rotation or attempted rotation of the wings or doors backward or in the wrong direction, a ratchet H is secured at the top of the doors, and a spring-actuated pawl h is caused to engage with the teeth of the ratchet when the doors are moved backward, but which will slide over the teeth when the wings are rotated in the right direction. A stay-spring L is secured to one side of the frame and kept in the path of the doors by the spring N, which will assist in preventing the backward movement of the doors if the ratchet should become inoperative, or before the end of the pawl drops behindatooth after the door had passed the lock and the bolts had resumed their former position.

By the use of my turnstile, the attendance of a gate-keeper is rendered unnecessary, as the device will operate automatically when the proper fare has been deposited and the door pushed away from the person entering, and it will only admit of the passage of one person at a time or for a single admissionfee.

Having described my invention, what I claim is 1. In acoin-operated stile, the combination, with a post, of a lock secured thereto, a series of wings or doors rotatable around the post and lock, two bolts within the lock, one end of each of which projects out into the path of the wings, and a latch for locking oneof the bolts, said latch being adapted to be released from the bolt by a piece of money introduced into the lock, substantially as described.

2. In a coin-operated stile, the combination, with a post, of a lock secured thereto, aseries of wings or doors secured to rings around the post by means of arms, arim in the inner edge of each door at the lock, two bolts in the lock, one end of each of which projects out into the path of the rims and one bolt having its end beveled or inclined and having its side within the lock provided with a shoulder, and a latch for locking the other bolt and adapted tobe re leased from the bolt by a coin forced against it by the shoulder on the first-mentioned bolt, substantially as specified.

3. In a coin-operated turnstile, the combination,with a series of doors movable around a common center, of a lock having bolts projecting into the path of the doors, a latch for locking one of the bolts and adapted to be operated by a coin, and a plate below the coin, the free end of which. projects into the path of the doors and is operated thereby to release the coin, substantially as specified.

4. In a coin-operated turnstile, the combination, with a series of doors movable around a common center, of a lock having a slot in its top, bolts projecting out into the path- 15 way of the doors, a'post having an arm for obstructing the slot, a laterally-projecting pin, and a plate pivotally' secured within the lock for engaging with the pin and having. its free end projecting out into the path of 10 the doors, substantially as specified.

In testimony whereofl aflix my signature in presence of two witnesses.

HENRY OASPAR.
